python的图像处理模块 除了opencv专门用来进行图像处理,可以进行像素级、特征级、语义级、应用级的图像处理外,python中还有其他库用来进行简单的图像处理,比如图像的读入和保存、滤波、直方图均衡等简单的操作,下面对这些库进行详细的介绍。 目录 一、PIL库 一、安装命令 二、Image模块 三、format类 四、Mode类 五、co...

Next, you pad your matrix on the right by appending the fourth column filled with zeros. After that, you reshape the matrix again by flattening it into another sequence of bytes, with an extra zero for every fourth element. Finally, you reinterpret the bytes as 32-bit signed integers ("<...
